[k8sattributes] Add e2e testing for profiles signal

[ChrsMark]

Right now, the e2e tests of the k8sattributes processor do not support profiles data type:

opentelemetry-collector-contrib/processor/k8sattributesprocessor/e2e_test.go

Line 112 in 36a7cf3

// TODO: add "profiles" to DataTypes once #36127 is resolved

This is because of #36127 which was closed.

The profiles signal is still in development and hence adding e2e testing for profiles is not a requirement for #44483.

This issue tracks this TODO for easier reference.
